Like most things, roofing shingles succumb to age. The average shingle lifespan ranges from 15 to 30 years. Some shingles, however, deteriorate sooner due to poor design, improper installation, lack of maintenance, and exposure to extreme weather conditions. Below are a few telltale signs that indicate the need for Burnaby roofing replacement.

Nails are Popping out of Shingles

Shingles are overlapping roof elements designed to shed water off the house. They are fixed with nails to ensure that they stay firmly in place despite strong winds and heavy rainfall. If you happen to discover some nails popping out of the shingles, it's a clear sign that they are close to coming off and are likely to get blown away by strong winds. In addition, the holes created by nails can serve as entryways for water, creating a ton of problems later on.

Erosion on the Corners of Shingle Flaps

Modern shingles have sharp corners on all of their flaps. These corners will erode over time or flake off when least expected. Never ignore such a sign because it can lead to massive damage and even physical injury.

Low Granules in Shingles

Shingles have granules for three main reasons: UV protection, fire resistance, and aesthetic purposes. Granule loss is a sign of critical shingle damage. Wind and rain push the granules down the roof's slope, thereby clogging the gutter. Granule buildup in gutters should be cleared away immediately before it becomes another concern.

Cracked Shingles

Shingles are among the strongest roofing elements, but they become susceptible to damage over time. Even though cracked shingles can be repaired using a sealant, they might not work as effectively as before; they may even give you a false sense of safety during severe storms. Damaged shingles should be replaced immediately to ensure your entire household’s protection.

These are just the four basic and most visible signs of roof damage. If you have already carried out a preliminary inspection but are still convinced that your roof is at risk of failing, then it would be best to acquire the services of a BC roofing contractor.
